I found that add but it's in Spanish and I don't see a promo code. I read a little Spanish but not enough to understand the whole add...
We flew volaris on our last trip, we were very impressed with the quality of the plain it self and the service. There is one carry-on allowed, and the first checked bag needs to be under 50 or 40 lbs. Very similar to the U.S. Standards. The only downside if you can call it that, is that all the onboard drinks and snacks have a price. We will totally fly with Volriis again.
